It seems counterintuitive that there would be mature galaxy when the Universe was very untested . However , an outside team of stargazer havediscovered fifteen galaxiesthat were already fully matured only 1.6 billion years after the grown bang . Much of what we have known about star and galaxy constitution states that the festering process take quite a longsighted time , which mean that some galaxies may age otherwise than what is auspicate by traditional modelling . The results were published inThe Astrophyiscal Journal Letters .
Prior to fifteen years ago , astronomers never thought that the early Universe would have had massive galaxies . It had been conventionally involve as a hotbed of ace and galaxy formation , with the earliest galaxies comparatively smaller than those that formed later . However , some began to hypothesise that galactic maturation may not occur at the same rate , and some might have gone through the cognitive operation much quicker . Karl Glazebrook , a Centennial State - author on the new paper , publish results in 2004of grounds of monolithic galax when the Universe was about 3 billion years honest-to-god . This Modern report found grounds of monumental galaxies that were ripe in one-half of that metre .
The squad was comprised of astronomer from Macquarie University , Swinburne University of Technology , and the Australian Astronomical Observatory ( AAO ) . The study involve psychoanalyze data from the Magellan Baade Telescope ’s FourStar television camera , the Hubble Space Telescope ’s Cosmic Assembly Near - infrared Deep Extragalactic Legacy Survey and Great Observatories Origins Deep Survey .
The galaxies themselves were very fainthearted and had to be figure in near - infrared wavelength . The stargazer discover the Galax urceolata as they were an average of 12 billion years ago , which made it very interesting when most of the lighter do back was the traditional Bolshevik which indicates that though the galaxies had 100 billion stars each , they were n’t forming any unexampled stars . For monolithic galaxies at the dawn of the Universe , having so many ripe stars was very uncharacteristic .
A region that has an exceptionally gamy rate of stellar establishment is described as a “ starburst . ” The squad believes the Galax urceolata may have had something like to a starburst stage which allow these galaxies to shape so much more quickly than the residue of the stars in the former Universe . There may have also been another influencing gene to force the galaxy to stop make new genius .
In social club to best read how these galaxy organise and mature , the squad will target galaxies that are more distant and thus , older . So far , the most upstage galaxy know to astronomers isAbell2744 Y1 , which was announced last month . It is around 13.2 billion years one-time .
